Oh this is easy. The init script calls s-s-d and does not check the return code (so always exits 0). I am just going to use set -e in the init script, only a couple tweaks are needed.
Please don't use set -e in init scripts. See Policy 9.3.2: Be careful of using set -e in init.d scripts. Writing correct init.d scripts requires accepting various error exit statuses when daemons are already running or already stopped without aborting the init.d script, and common init.d function libraries are not safe to call with set -e in effect. For init.d scripts, it's often easier to not use set -e and instead check the result of each command separately. Not mentioned there is another problem, namely that LSB mandates particular exit codes for particular conditions in init scripts, and set -e will not produce the correct exit codes.

I thought that start-stop-daemon (and status_of_proc) returned the correct codes, and whatever it returns you can relay / let the shell catch? The script is here (https://github.com/cgmanager/cgmanager/pull/14/files), if you wanted to take a look.
